Thanks for information - I tried the above scan-ware and it did remove a lot of unnecessary stuff
However, the problem still exists - PC continues to blue screen/crash or the application just hangs.
Here are the error messages from the event viewer:
Error code 1000000a, parameter1 0000ffdf, parameter2 00000002, parameter3 00000001, parameter4 806ffa8e.
